# Chapter 4. Configuration

KDE su comes with a control module named kcmkdesu. You can find it in the K menu under Settings->Applications->KDE su. You can change the following things:

- Echo mode. This is how characters you type are echoed to the screen. Possible choices are: one star per character, three stars or no echo at all. The default is one star per character.

- Keeping passwords. You can instruct KDE su remember passwords you enter by checking the "keep password" check box. If this checked, you can enter a timeout value in the text field below it. This is the amount of time, in minutes, that the password will be remembered. The default is not to remember passwords.
